Installation & Service Manual

Although the diagram shows mechanical relays, the actual outputs are implemented with
solid state relays. The solid state relays are bidirectional; either polarity voltage can be
applied. If the switcher GPI/Relay Tally outputs are used to drive downstream DC relays, be
sure to install diodes across the relay coils to clamp inductive spikes. Shielded cable is
recommended for the connection from the switcher to the user Relay Tally system.
